Nonhydrogen-bonding liquids

The combination of a high critical surface tension intercept and a split in the contact angle data for the hydrogen-bonding and nonhydrogen-bonding liquids is the best indicator of the presence of accessible... [Pg.171]

Since solvatochromic parameters are derived from direct measurements of the energy resulting from intermolecular interaction, they can be used to predict solubility, which is determined by solute-solute, solvent-solvent, and solute-solvent interaction energies. For nonself-associated liquid aliphatic compounds with a weak or nonhydrogen-bond donor (Taft etal., 1985 Kamlet etal., 1986), the solubility in water at 29S was related to molar volunWjf, hydrogen-bond basicity j and polarity/polarizability (jf) by a linear solvation energy relationship (LSER) as in Equation 3.55 ... [Pg.52]

Slowly advancing contact angles were determined with pure reference liquids placed dropwise on each specimen surface (I, 2, 3) these liquids included hydrogen-bonding and nonhydrogen-bonding compounds with a wide range of surface tension and structural type. Each cited... [Pg.162]

The V and 5 are pure-component properties. There are no mixture parameters to adjust for data htting in Equation (4.357), Equation (4.360), and Equation (4.361). The regular solution equation is predictive based on pure-component liquid properties. It is generally useful for a first-order estimate for nonpolar, nonassociating, nonhydrogen bonding solutions. RT In y of a regular solution by Equation (4.357) is not dependent on T,... [Pg.334]
